Theory:

There are millions of organic carbon compounds found in nature as well as those created by humans. Organic carbon compounds are carbon compounds that have been linked with other elements such as hydrogen, oxygen, nitrogen, sulphur, and so on.
 
Organic compounds are inevitably connected to human life. They are used or associated with mankind at all stages of life.
 
The following are various classes of organic compounds and their applications in everyday life.
 
Hydrocarbons:
  • LPG, petrol, and kerosene are examples of hydrocarbon fuels.
  • It is used as raw materials for a wide range of important synthetic materials.
  • Tyres and plastic containers are examples of polymeric materials that are made up of hydrocarbons.
Alcohols:
  • Alcohol is used as raw material for a wide range of important synthetic materials.
  • It is used as a solvent and as an antiseptic agent. 
Aldehydes:
  • It is used as a disinfectant
  • Aldehydes are used as raw materials for a wide range of important synthetic materials. For example, formalin is made from formaldehyde which is used for preserving biological specimens.
  • Perfumes, cosmetics, and dyes all contain benzaldehyde. It is used to add almond flavour to food products and as a bee repellent.
Ketones:
  • It is used as a solvent and a stain remover. For example, acetone is used as paint thinner and as nail polish remover.
  • Ketone is used in medicine for chemical peeling and acne treatments.
  • Another important ketone is cyclohexanone, which is primarily used in the production of nylon.
Ethers:
  • It is used as an anaesthetic agent and as a pain killer. 
  • Spirit of Ether: The analgesic (pain killer or hypnotic effect) is a solution of one part diethyl ether and three parts ethanol.
  • Ethers are used to treat diseases such as scurvy and pulmonary inflammation.
Esters:
  • Esters are present in all cooking oils and lipids.
  • Esters are used to making surfactants such as soap and detergents.
  • Nitroglycerin and other nitrate esters are used as explosives.
